Sarrasine is published in 1831, and is part of the Scènes de la Vie Parisienne (Scenes from Parisian Life) subseries of La Comédie Humaine.
The nameless narrator attends a ball held by a wealthy Parisian family whose fortune comes from a work of art, and there meets an extraordinary old woman who bears a strange resemblance to the statue depicted in the painting.
On the surface it is a tale of sexual androgyny, the power of love, and its bitter aftermath. But it can also be read as a study of the force of art on society and the immortality of beauty.
Roland Barthes' analysis of Sarrasine in his S/Z is of great interest.
